Venerable relates a story of his contemplation as he encountered a long street of Betel Nut Beauties while he was keeping his precept.

My understanding from the video is that with the awareness that all of us want to relieve ourselves of suffering and gain happiness. This motivation guides all our actions. However, some (I would say most) of us have not found the correct way to eliminate suffering and achieve happiness.
With this awareness, it will be much easier to not get angry or frustrated at other people. In fact, it will be easier to be sympathetic and show kindness to others. This is because we are all driven by the exact same motivation. Just that we are lucky to have the Dharma and the Teachers guiding us on this.
